Everyone loves these - especially when they are with Change Research!
CNBC/Change Research Poll in Arizona, Florida, Michigan, North Carolina, Pennsylvania, and Wisconsin: May 1-3, 2020
Trump 48
Biden 45
Should make it clear though that this sample seems VERY pro-Trump. Just look at the favorable ratings:
Donald Trump 46/50 (-4)
Joe Biden 36/55 (-19)
Bernie Sanders 32/55 (-23)
Trump's approval in this poll is also 49/51 which... does not align at all with other specific battleground polls we've gotten.
